Abstract: 1,139,068. Casting processes. HENRY WIGGIN & CO. Ltd. 18 July, 1966 [16 July, 1965], No. 30361/65. Heading B3F. In the casting of metal by remelting an ingot into a mould by passing an electric current through the ingot and mould via a slag in the bottom of the mould, the slag is poured into the mould in a molten state to facilitate starting the casting process. The electrode, formed by the ingot being remelted, is positioned at a pre-set distance from the top of a starter pad in the bottom of the mould before the pouring in of the molten slag. The starter pad may be made of a material of similar composition to the ingot being remelted so that it can be assimilated into the finished cast ingot and is in the form of a cone or pyramid with its apex presented to the electrode. In examples described an ingot of material containing 32% copper and 63% nickel is remelted.

Title: Improvements in and relating to the production of diketene
Inventor: OSMOND ERIC WILLIAM
IPC: C07C45/88
Filed: 1950-12-13
Abstract: In a continuous process for the production of diketene by polymerizing a solution of ketene in a solvent the ketene solution is produced continuously by simultaneously feeding the liquid solvent and ketene in the gaseous state and under reduced pressure into a vacuum pump, the resultant ketene solution is continuously withdrawn from the pump substantially at atmospheric pressure and continuously circulated in a closed system where polymerization of the ketene to diketene takes place, and part of the diketene solution is withdrawn at a suitable point in the system for recovery of the diketene.  In an example, in accordance with the flow sheet accompanying the Provisional Specification, ketene gas under reduced pressure is drawn from a cracking plant through a pipe 1 into a vacuum pump 2 where it is mixed with liquid diketene drawn in through pipe 3.  The mixture of gas and solution leaves <PICT:0702913/IV(b)/1> the pump 2 at atmospheric pressure and passes through a pipe 4 to a liquid-gas separator 5.  The solution passes from the separator 5 to a reservoir tank 7 through a pipe 6, while waste gases are withdrawn from the separator 5 through a pipe 8 and passed to an acetic acid scrubber and atmosphere.  From the reservoir 7 the solution passes into a pipe 9 and part of the diketene solution is continuously tapped off at 10 for recovery of the diketene while the remainder passes to a brine-cooled liquid cooler 11 and thence into pipe 3 for feeding into pump 2.  Polymerization of ketene takes place continuously throughout the system.  Specifications 410,394, 498,280, 550,486 and 694,899 are referred to.

Abstract: 965,726. Protective arrangements. MULLARD Ltd. Aug. 10, 1962, No. 30788/62. Heading H2H. [Also in Division H3] In a transistor protection circuit a control transistor T 1 , Fig. 1, is normally biased to be non-conducting, but when a fault exists in the circuit of the transistor to be protected and a rectified voltage V 2 , derived from the signal current through the protected transistor and applied to the control transistor T 1 , exceeds a rectified signal V 1  derived from the load resistance of the protected transistor and also applied to the control transistor, current flows through the collector of the control transistor, is smoothed and then employed to limit or cut-off the signal gain of at least one transistor stage preceding the protected transistor. The protection circuit of Fig. 1 may be used to protect the transistors of a class B power amplifier, Fig. 2. As shown, the signal across load R7 of preamplifier stage T 3  is fed to amplifier block A and then to the primary winding of input transformer I T  of an output stage comprising push-pull connected transistors T 4 , T 5  to be protected. The voltage developed across resistive load R 13  is fed through diode D 1  and resistor R 1  to the base of control transistor T 1  to the emitter of which is applied a signal voltage developed across resistor R 11 . The valves of resistors R 1 , R 2  are selected so that transistor T 1  is normally non-conducting but when resistor R 13  is short-circuited and the voltage across R 11  exceeds the voltage across R 13  transistor T 1  conducts. Its collector current I c , smoothed by capacitor C 3  and amplified by transistor T 2 , is applied to the collector of transistor T 3  so that the voltage drop across R 7  will increase so as to limit the signal gain of transistor R 3  thereby reducing or cutting-off the signal applied to transistors T 4 , T 5 .

In a pipe support wherein a chain 4 passes over an eccentrically mounted chain wheel 1 and is connected at one end to a pipe-line and at the other end to a supporting spring 6, the wheel has an inset cam-shaped recess D to one side of the minimum distance between the axis and the periphery of the wheel to increase the range of movement of the wheel and to counteract the varying tension of the spring 6. The leverage due to the weight of the piping on one side of the wheel 1 is counterbalanced by the opposing leverage accompanying the variation in tension of the spring 6 due to expansion and contraction of the piping. The chain 4 may engage a jockey pulley 9 mounted together with the wheel 1 on a bracket 2 from which is suspended a rod 7 for compressing the spring 6. Extended teeth 10 on the wheel 1 allow the wheel to be adjusted to various positions on the chain.

Filed: 1928-10-25
Abstract: 324,391. Johnson, E. M., and Associated Electrical Industries, Ltd. Oct. 25, 1928. Driving-arrangements.-Relates to power systems of the type in which a main prime mover, such as a reciprocating engine 1 driving a propeller shaft 2 direct, exhausts into a turbine 4 which drives the same shaft 2 through an electric coupling comprising a generator 8 and a motor 9. When the reciprocating engine is reversed the turbine continue to rotate in the same direction, and it is necessary to reverse or disconnect the electric coupling. This is effected by the apparatus shown in Fig. 2 by means of which the alteration of the coupling is made during a definite predetermined portion of the travel of the reversing control mechanism of the engine 1. An arm 18 forming part of this control mechanism is arranged to actuate a switch 13 to reverse the electric coupling by causing a pin 22 on an arm 20 to engage a notch 23 in a switch member 24. The reversing switch 13 may control the field winding of the generator or that of the motor or may control the connection between the generator and the motor. Live steam may be supplied to the turbine 4 through a pipe 7, and in this case a lug 26 connected with the stop valve 7<a> is arranged so that the engine 1 cannot be reversed until the valve 7<a> has been closed. Either engine may be run independently. A bye-pass valve 28 leading to the condenser 5 and a stop valve 29 may be provided.

In the hydraulic pump or turbine or pump-turbine shown, the driving or driven shaft S is connected to oppositely rotating rotors A, B through epicyclic differential gearing comprising planet gears 2, 3 freely mounted on shafts carried by a planet carrier disc c. Gears 2 mesh with a sun gear 1 fixed to the shaft S and with an internal ring gear 5 fixed to the hub of rotor B. Gears 3 mesh with a sun gear 4 fixed to a stationary shaft F and with an internal ring gear 6 fixed to the hub of rotor A. Rotor A is journalled on shaft F, the latter being carried by spider arms G1. A hub carried by spider arms G2 provides bearings for shaft S and rotor B. The shaft 7 of the planet carrier disc C is supported by the shafts S and F. Rotors A and B run in opposite directions with equal torques, the speeds being adjusted by the differential gearing so that the whirl imparted to the water by rotor A is removed by rotor B. Alternatively, a slight residual whirl may be imparted to the water by making the two sets of sun and planet gears of different diameters.

Abstract: 227,109. Girardelli, R. Dec. 31, 1923, [Convention date]. Milling-machines.-In a templet-controlled copying-machine the work P, profiled by a tool F, is mounted upon a rotary table G carried on a slide which is traversed on a bed T by a screw v driven from a three-phase motor M. The latter is controlled by a switch I operated by an electromagnet E, the circuit of which includes a battery Z, contact R and templet S. When the contact R engages the templet, the switch is brought to the position shown and the motor is driven to move the work away from the tool. As soon as the templet leaves the contact, the circuit of the electromagnet is broken and the switch I is moved by a spring m to reverse the direction of the motor. The templet may also have an axial movement relatively to the tracer so that three-dimensional copying may be effected.
